Any Changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
To maintain compliance with FCC’s RF Exposure guidelines, This equipment should be installed and
operated with minimum distance between 20cm the radiator your body: Use only the supplied antenna. This
product should not collocate with other radio. If the FCC identification number is not visible when the module
is installed inside another device, then the outside of the device into which the module is installed must also
display a label referring to the enclosed module. This exterior label can use wording such as the
following:"Contains Transmitter Module FCC ID: 2AH9Q-BLEV1-C"or"Contains FCC ID: 2AH9Q-BLEV1-C".
The module’s antenna is internal antenna, and the antenna can’t be replaced.
(a) The module should not collocate with other wireless radio
(b) PCB antenna of antenna OEM should be use. Antenna Gain is 0dBi to connect with the antenna seat.
measures:
-Reorient or relocate the receiving antenna.
-Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
-Consult the dealer or an experienced radio/TV technician for help.
Note:
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
- Consult the dealer or an experienced radio/TV technician for help.
